The Piqua Nuclear Power Facility was a nuclear power plant which operated just outside the southern city limits of Piqua, Ohio in the United States. The plant contained a 45.5-megawatt (thermal) organically cooled and moderated nuclear reactor (terphenyl, a biphenyl like oil) . The Piqua facility was built and operated between 1963 and 1966 as a demonstration project by the Atomic Energy Commission. The facility ceased operation in 1966. It was dismantled between 1967 and 1969, and the radioactive coolant and most other radioactive materials were removed. The remaining radioactive structural components of the reactor were entombed in the reactor vessel under sand and concrete. ==Background== The plant was first proposed February 1, 1956 when the local public utility company in Piqua, Ohio proposed to build a 12,500 kilowatt nuclear power plant using an organically moderated reactor by asking to join the U.S. government's small reactor construction program which provided joint government-utility participation.〔''The Lima News'', February 2, 1956, page 3, column 2〕 Seven power plant applications were received by the Atomic Energy Commission (AEC). The municipalities were revealed when Senator Clinton P. Anderson of New Mexico accused the AEC of trying to impose an 'absolute Iron Curtain around thought' regarding nuclear secrecy.〔The ''Billings Gazette, February 8, 1956, page 1, column 1〕 At the same committee meeting the locations of the seven proposed power plants were announced: * Anchorage, Alaska * Elk River, Minnesota * Gainesville, Florida * Hersey, Michigan * Holyoke, Massachusetts * Piqua, Ohio * Orlando, Florida By September 27, 1956 the AEC authorized contract negotiations for the $8M plant. $4M would come from the AEC to finance the reactor construction and $4M would be from the city of Piqua for facilities, land and building. The Atomics International division of North American Aviation was selected to design the plant.〔The ''Portsmouth Times'', September 28, 1956, page 26, column 2〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Piqua Nuclear Generating Station」の詳細全文を読む スポンサード リンク
